SPECIFICATION forming part of Letters Patent No. 699,832, dated May 13,1902.

Application filed March 30,1901. Serial No. 58,591. (No model.)

To a/ 'LU/wm t puny concern.-

Be it known that I, PETER BRoADBooKs, a citizen of the United States,residing at Batavia,county of Genesee,and State'of New York, haveinvented a certain new and useful Improvement in CombinationlVire-Cutters and Pliers, of which the following is a specification.

My invention relates to a new and useful improvement in combinedwire-cutters and pliers, and has for its object to so construct a deviceot' this character, which is commonly called linesmans pliers, that itwill be light in weight, but have greater strength and power than thelinesxnans pliers now in use.

A further object of my invention is to provide wire-cutting plates whichcan be removed whenever they become damaged or in need of sharpening andby pivoting said side cutting-plates at the same point as the handlesare pivoted will allow t-he cutting to be done nearer the fulcrum-point.

y Another object of my invention is to produce a device of thisdescription which, with all its advantages, will be exceedingly simplein construction, and consequently cheap to manufacture.

W'ith these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a side view of my pliers, showing the jaws closed. Fig. 2 isa side view from the opposite side of Fig. l, showing the Fig. 3 is anedge view of my pliers, the handles being broken away. Fig. 4 is a viewof the opposite edge of my pliers; Fig. 5, a section on the line 5 5 ofFig. l; Fig. 6, a section on the line 6 6 of Fig. l; Fig. 7, a side viewof my pliers, showing the same used with compound leverage. Fig. 7 is aview in elevation of one of the jaws; Fig. 8, aview of the opposite sideof the compound lever-pliers; Fig. 9, an edge View of the same. Fig. 9is an edge View of the jaw shown in Fig. 7f; Fig. 10, a side view of a4pair ofpliers,showing the lnodiiication wherein the side plates arepivoted independently of the handles; and Fig. ll is a view in elevationofthe pliers shown in Fig. l0 looking in the direction of the arrow. i

In carrying out my invention as embodied in Figs. 1 to G, inclusive, Aand B represent the handles of a pair `of pliers which are led togetherand pivoted at C. D and E'are the jaws, which are formed with thehandles A and B, respectively. Fand Gare side plates, which are rivetedto the jaws D and E at the pointsfand g. The heel ends of these sideplates are pivoted together at the point C upon the same pivot as thehandles A and B.

These side plates meet when the pliers are closed at the line I-I andare milled or ground to knife-edges, forming wire-cutters. I is astrengthening-plate upon the opposite side of the jaws of the pliers,which is secured to the jaw E by the rivet g, which passes through thesaid jaw. The heel end of this plate I is also pivoted at the point C tothe same pivot as are the handles A and B. That portion of the handlessurrounding the pivotpoint C is formed concentric with such pivot, andeach pair of pliers are cut away one-half their width, so as to fittogether and not cause the pivoted part to be of any greater width thanthe handles or jaws. The inside of each of the jaws and also the upperpart of these concentric portions are cut away, as indicated at P, to apoint comparatively near the pivot C. This is -for the purpose ofallowing the wire to be cut at a point near the fulcrum, which willenable the operator to use more force. Each of these circular portionsof the handles has slots .I cut in the edge of the same diagonally.These slots are adapted to register with one another when the pliers areopen to their full extent for the insertion of any wire which is desiredto be sheared off, andwhen the pliers are closed the wire will besevered by reason of the cutting edges of the slots passing one another.This manner of shearing wire is well known and in use in ordinarypliers; but the improvement in my pliers iu connection IOO wth theseshearing-slots is that I provide stops upon the opposite edge of thiscircular portion K, so that when the pliers are open these'stops willcome together and limit the movement ot' the jaws, and when in thisposition the shearing-slots J are in exact register with one another.

In Figs. 7 to 9, inclusive, I have shown my invention in use Where it isdesigned to employ compound leverage instead of direct. In thisconstruction the handle B and jaw E are formed in one piece, as in theconstruction last described. The handle Al is separate and pivoted tothe member L, secured on the heel end of the jaw. The extension D has apivotal pin M, working in a slot of the member Said member A' has itsupper end pivoted at N to an extension L, formed with or rigidlyattached'to the member E.

In Figs. l0 and l1 I have illustrated the modification wherein insteadof pivoting both side cutting-plates upon the pivot C, I pivot onecutting-plate F upon the pivot, the upper end of this cutting-platebeing riveted to the jaw E at g, as before described, but the otherplate G' may be either formed with the jaw D or be a separate plate, asillustrated in the drawings, and'secured to the jaw D by a dovetailtongue and groove.v A rivet passing 3`o through this cuttingfplate G andthe jaw D serves to hold the same in place. The advantage of thisconstruction is that the cutting-plate F', which is pivoted upon thepivot C, need not be cut away at the pivotal point, but be of the samewidth throughout. This will add additional strength and simplify theconstruction.

Of course it will be understood that it is not necessary to have thejawsE and D made integral with the handles A and B; but they could besecured to the handles by riveting or other means, and this wouldprobably be the construction employed in making very light pliers, suchas are commonly)7 called hollow-handle pliers.

The advantages of my invention are as follows: By pivoting the sideplates F and G together upon one side of the main joint ot' the tool andby securing the side plate I to one of the jaws and pivoting the sameupon the opposite side of the main joint strength is added at the pointmost needed. By holding the two members of the pliers more rmly and alsokeeping the jaws from twisting sidewise where the greatest strain comesand by reason of making the side plates F and G the .cutting-plates andby pivoting them together at their heel ends one-half ot' the strainbrought to bear upon the main jaws will be reduced. A further advantageis that in my construction the side cutters are much nearer the fulcrum,and the power is consequently increased in the same proportion and alsoallows the tool to be made much lighter and yet do more work. A furtheradvantage of my construction is that but one die is required in makingboth members of the pliers, as illustrated in Figs. l to 6, inclusive,and Figs. l0 and 1]. Also-one die will make both cutting-plates, thebevel for the cutting edge being milled. Another advantage of myinvention is that by making the cutting-plates removable new plates canbe easily substituted with but little cost, thereby saving expense tothe user of these tools.

Of course I do not wish to be limited to the exact construction shown,as slight modifications could be made without departing from the spiritof my invention.

Having thus fully described my invention, what I claim as new and usefulisl. In combination, two levers pivoted together, jaws formed with orsecured to said levers,'two side plates secured one to each of the jawsupon one side thereof, the heel ends of said side plates being pivotedtogether upon the outside ot' the main joint of the pliers, cuttingedges formed upon each of said side plates, a plate secured to one ofthe jaws upon the opposite side thereof, the heel end of said platebeing pivoted upon the same pivot as the jaws, substantially asdescribed and for the purpose specified.

2. In combination, a pair of handle-levers led together and pivoted toeach other, a pair of jaws formed with or secured to said levers, tworemovable plates, one secured to each of the said jaws upon one sidethereof, the heel ends of said plates being pivoted together upon oneside of the pivotal point of the jaws, cutting edges formed upon saidplates at the point where said plates meet when the pliers are closed, astop formed upon each member of the pliers, said stops adapted to engageone another 'when the jaws are open to a certain point for the purposeof limiting the movement of the same, substantially as described and torthe purpose specified,

3. In combination, a pair of handle-levers led together and pivoted toone another, concentric portions formed concentric with the pivotalpoint formed with each of said levers,- cavities formed upon the insideof each of the jaws and also the upright part of the concentric portionsto a point comparatively near the pivot, stops formed upon one edge ofeach of said concentric portions and adapted to engage one another whenthe jaws of the pliers are open to a certain point, diagonal slotsformed in the opposite edge of the concentric portion for the purpose ofcutting or shearing wire, said diagonal slots adapted to register withone another when the aforesaid stops upon the opposite edge are incontact with one another, jaws formed with or secured to thehandlelevers,two side plates, one secured to each of said jaws, the heelends of said side plates being pivoted together, cut'- ting edges formedupon said sideplates,a plate upon the opposite side of the pliers, said'xedmysgnature in the presence of two subplate being secured to one ofthe jaws, the serbing witnesses.
